Example Embodiment

[0025] Example one

[0026] figure 1 This is a schematic flow chart of a method for preparing polysaccharides from Astragalus sinensis in an embodiment of the present invention. figure 1 As shown, the preparation method of the polysaccharides from Astragalus sinensis includes:

[0027] Step 10: Crush the dried sand to attract grass to obtain sand to attract grass powder;

[0028] Specifically, the dried sand-inducing grass is pulverized, and the pulverized sand-inducing grass powder is passed through a 40-mesh sieve, and after sieving, the sand-inducing grass powder meeting the requirements is obtained.

[0029] Step 20: extracting, filtering, and concentrating the A. sylvestris powder to obtain a crude polysaccharide solution of A. sylvestris;

[0030] Further, the extracting, filtering, and concentrating the sand-inducing grass powder to obtain the sand-inducing grass crude polysaccharide solution further includes: using petroleum ether to reflux the sand-inducing grass powder to re...

Example Embodiment

[0042] Example two

[0043] This embodiment provides a plant salt-tolerant regulator, which contains the Astragalus polysaccharide of claims 1-6.

[0044] Specifically, the embodiment of the present invention provides a new application of the polysaccharides of A. sinensis, which can be used to prepare a plant salt tolerance regulator. At the same time, the polysaccharides of A. sinensis are compounded with a surfactant to prepare a salt tolerance regulator. It can improve the comprehensive resistance of plants to salt stress and ensure the normal growth and development of plants. The polysaccharide of A. sylvestris can regulate ion transport in plants to improve the salt resistance of plants. On the one hand, the polysaccharide of A. sylvestris stores excess Na+ in the roots, reduces the stress of Na+ on the stem and ensures the physiological functions of the plant leaves. On the other hand, the Astragalus sinensis polysaccharide can induce plants to transport excessive Na+ ions ...

Example Embodiment

[0050] Example three

[0051] In order to have a clearer understanding of a plant salt tolerance regulator provided in the embodiments of the present invention, specific examples are used to describe the embodiments of the present invention in detail below.

[0052] Dissolve 100 mg of the A. sylvestris polysaccharide in 800 ml of distilled water, stir evenly, and finally dilute the volume to 1L with distilled water. After stirring, make the concentration of the s. sphagnum polysaccharides 100-1000 mg / L to prepare the Salt-tolerant regulator A; or to add surfactants to the salt-tolerant regulator A, the surfactant is selected from one or more of Tween series, Span series, OP series and / or NP series , The concentration of surfactant is 1000-20000mg / L to prepare anti-salt regulator B.

[0053] Use the salt tolerance regulator A or B to spray the wheat seedlings in the seedling stage. The specific process is: sterilizing, soaking, and accelerating the germination of the wheat seeds. Whe...

Abstract

The invention discloses a tournefortiasibirica polysaccharide preparation method and a plant salt-resistant regulator. The tournefortiasibirica polysaccharide preparation method comprises the following steps: crushing dried tournefortiasibirica to obtain tournefortiasibirica powder; performing extraction, extraction filtration, condensation on the tournefortiasibirica powder to obtain a coarse tournefortiasibirica polysaccharide solution; performing deproteinization on the coarse tournefortiasibirica polysaccharide solution to obtain a deprotein coarse tournefortiasibirica polysaccharide solution; performing alcohol precipitation and lyophilization on the deprotein coarse tournefortiasibirica polysaccharide solution to obtain coarse tournefortiasibirica polysaccharide; removing pigment ofthe coarse tournefortiasibirica polysaccharide through macroporous resin to obtain tournefortiasibirica polysaccharide, the technical problem that green natural salt resistant agent taking the tournefortiasibirica polysaccharide as raw material is not found in the prior art is solved, the tournefortiasibirica polysaccharide preparation method has the advantages of simple extraction process, safe and environmental protection and remarkable effect, and is suitable for being applied to the technical effects of development and application of the plant salt-resistant regulator.

Description

technical field [0001] The invention relates to the technical field of plant regulators, in particular to a method for preparing polysaccharides from Phyllostachys sativa and a plant salt-resistant regulator. Background technique [0002] Tournefortiasibirica (Tournefortiasibirica) is a perennial wild herb of the Boraginaceae genus Tournefortiasibirica, also known as Zidancao, Siberian Zidan, etc. Sandgrass is a species in central Asia in the temperate zone. It is mainly distributed in the coastal and inland areas of China and neighboring countries at 30°-45° north latitude. Most of them are in the coastal area. Barren resistance. Sand grass not only plays an important ecological role in windbreak and sand fixation, beach protection and vegetation restoration, but also can be used as medicine, feed, honey plant and green manure, and has broad application prospects in agricultural production. It is reported that the vegetative growth period of S. sativa has higher content o...
